The dense busbar trunking junction box is directly connected to the CESKO busbar trunking through connectors,with corresponding interlocking,and the junction box cannot be pulled out without disconnecting.Generally,three plug-in boxes can be connected to a 2-meter straight bus duct because the current of the plug-in box is small,and cables are usually used for external output.

　　For the docking type bus duct,the end parts of the two bus conductors to be connected should be aligned parallel to each other,and then the copper connecting piece and insulation partition should be inserted into the gap between the bus ends(one copper connecting piece should be clamped on each side of the bus,and an insulation partition should be placed between the copper connecting pieces).After confirming that there is no problem,the insulation bolts should be inserted,and attention should be paid to whether the connection holes of the copper connecting piece,bus end,and insulation partition are aligned,whether the copper connecting piece and insulation partition are in place,and tighten the bolts.

　　Dense bus duct

　　First,check the conductor connection surface and connector at one end of the bus duct for any collision hazards.After confirming that there are no problems,preliminarily connect the two bus ducts to the connector bus.The bus duct conductor should be inserted into the connector,and after ensuring that it is in place,use a torque wrench to lock it.
